ings, forming a part of this specification, in

which Figure 1 shows aplan of my invention; Fig. 2, section through line (6 b,,thuiub-mit in cle- 'vation.

Same letters show like parts.

My invention consists of an improvement in circular saw-guides readily adjustable and easily taken out of the way when the'saw is to be removed from the arbor. It will be un derstood by reference to the annexed drawings.

At a is shown a box or casing closed at the top but open at the bottom to allow the escape of dust, &c., which might otherwise clog my device. This casing is secured to the ma chineframe by bolts passing through slots to allow adjustment as the saw wears. Within the casing are independent levers b c, extending past the periphery of the saw, and having cavities near their ends, as common, to receive the wooden pins or pegs which come in contact with it. These levers are pivoted at d (I. At cf, in the top of the box a, are slots out upon a curve struck from the pivots d d, respectively, as centers. Through these slots pass bolts 5 72-, entering threaded holes in the levers be, and provided with broad shoulders 93, and also, if desired, with washers 7', thus giving a broad bearing-surface upon the top of the casing sufficient to resist any tendency of the levers to shift their position. By means of these slots and bolts or thumb-nuts the levers may be securely fixed in the position desired, while if it becomes necessary to remove the saw for any reason, the outer lever, 0, can be readily thrown to one side by loosening its nut.

I do not claim the devices shown' in the patent of H. 0. Berry, wood-turning lathe, No. L

63,836, April 16, 1867, consisting of upright jaws carrying friction-rolls, against which the object in process of turning rests as asupport instead of being embraced, as in inyinvention. "M y device is for an entirely difierent purpose,- and is radically different both in construction and operation. c

\Vhat I claim as my invention is-+ In a saw-guide, the'combination of the easing a, secured to the frame of thema-chiue by slots and bolts, allowing adjustment as the saw wears down, inclosing levers b a, one on each side of said saw, pivoted to said casing at d (I, said casing being provided with curved slots cf, struck fromsaid pivots, respectively, as centers, with thunib-nntsor bolts 5/ 71, passing through said slots and into said levers, whereby said levcrs maybe fixed in any required position.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day "of June, 1883.
